Difficulty

Diablo 3 features several different Difficulty settings, which can be used to increase the challenge of the game, or to increase the loot and experience awarded from playing.

In Patch 2.0.3, Blizzard made major changes to difficulty settings. Rather than having each difficulty cater to a specific level range, all monsters now scale automatically to a player's level, or the average party level for a group. The difficulty settings now repesent how challenging the monsters will be for the player at that given level.
